Help determine the costs of production incurred by firms.
Higher resource prices raise production costs, which in turn lower profits and lower the incentives to increase supply.
For example, as the price of peanuts increase, the cost of making peanut butter will increase. Therefore, as a result there will be a reduction in the supply of peanut butter.
Technology:
Improvements in technology improve the ways of production by allowing firms to produce outputs using fewer resources. Using fewer resources reduces production costs which increases supply.
An advance in technology makes it possible to supply more of a good
A decline in technology means producers will supply less of a good.
For example, when the cotton gin was invented it lowered production costs by making it more efficient to separate the cotton fiber from the seeds than hand picking it. This resulted in an increase in the supply of cotton to be used for clothing purposes.
Taxes and Subsidies:
If the government places a tax on the production of a product supply decreases.
If the government subsidizes the production of a product supply increases.
For example, if the government were to place a tax on steel, the production price of cars would increase. Therefore, the supply of cars would decrease.
Prices of other goods:
Firms use resources to produce alternative goods.
For example, higher prices of "other goods" such as carrots and cucumbers cause firms to produce more of these goods to increase profits. This would result in a decline in the production of goods such as celery.
Producer expectations:
Changes in expectations about future prices of a product firms produce affect the sellers willingness to produce a certain product.
For example, farmers anticipating a higher corn price in the future might with hold some of their current corn harvest from the market in order to have a greater profit later in time.
These five supply determinants cause the supply curve to shift
The supply determinants are assumed to remain constant with the construction of this supply curve. The supply determinants are assumed constant for two reasons:
To isolate the law of supply relation between supply price and quantity supplied.
To systematically analyze what happens to supply when each determinant changes.
A change in any of the five determinants can cause either an increase in supply or a decrease in supply
Increase in Supply: An increase in supply is a rightward shift of the supply curve. An increase in supply means that for any price, for every price, sellers are willing and able to sell more of the good.
Decrease in Supply: A decrease in supply is a leftward shift of the supply curve. A decrease in supply means that for any price, for every price, sellers are willing and able to sell less of the good.
Supply in the news:
In Scotland, recently there has been a significant drop in the supply of affordable home in the private sector. However, the public sector has supplied a greater number of affordable homes recently. There is major concern for the for the future of affordable housing in Scotland because the cuts in government funding on affordable housing (Producer Expectations), there is an expectation to be a shortage of housing in the near future. "Fall in Supply of New Houses in Scotland" On the other hand, in the United States government granted subsidies that have lowered the production costs of different farm products: soybeans, cotton, wheat and corn. The lowered production costs make it less expensive for farms to expand and produce more of these products. As a result, the supply of these products will increase. "Down on the Farm"
